Application filed November 4, 1920. Serial 110,421,766.

T0 aZZ whom it may concern:

Be it known that 1, WILLIAM G. KENDALL, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented a new and Improved Press, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved press more especially designed for forming powder puffs, such, for instance, as shown and described in the Letters Patent of the United States, No. 1,374,746, granted to me on April 12, 1921.

Another object is to provide a press which permits of turning out a large number of powder puffs or similar articles in a comparatively short time and without requiring the use of highly skilled labor.

Another object is to accurately and se curely unite the component parts or sections of the powder pufi.

With these and other objects in View, the invention consists of certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the improved press with parts shown in section;

Figure 2 is a front elevation of the: same;

Figure 3 is an enlarged sectional side elevation of the dies with the powder puif sec tions in position therein;

Figure 4 is a similar View of the same with the powder puff sections united;

Figure 5 is a plan View of the lower die with one of the powder puff sections in position therein, parts being shown broken out;

Figure 6 is an inverted plan View of the upper die with the other powder puff section in position therein, part being broken out; and

Figure 7 is a perspective View of the finished powder puff.

On a suitably constructed stand 10 is mounted a bed 11 supporting a lower die 12 preferably of cylindrical shape and adapted to contain in its upper portion one powder puff section 13 to be united with another powder puff section 14 contained in the lower portion of an upper die 15 likewise of cylindrical shape. The upper end of the lower die 12 is provided with a seat or shoulder 16 on which is remo-vably seated the lower end of the upper die 15 so that the axes of the dies 12 and 15 coincide when in operative position, as shown in'Figures 1, 2, and 4. V

1n the lower die 12 is mounted a plunger or anvil 20, on the top of which rests the powder puff section 13 during the time the section 14 is united with the section 13, as hereinafter more fully explained. The plunger 20 is provided on its upper end with an annular flange 21 adapted to be seated on the top of a shoulder or collar 22 formed on the inner face of the lower die 12 intermediate the ends thereof to hold the plunger 20 in lowermost position with the powder puff section '13 contained in the upper portion of the die 12. The bottom 23 of the plunger 20 is removably fastened in place by screws 24 and this bottom 23 projects beyond the peripheral face of the plunger to form a flange to abut against the under side of the shoulder 22 at the time the plunger 20 is pushed upward in the die 12 to eject the finished powder puff therefrom. The bottom 23 is provided with a depending centering pin 25 engaging a recess 26 formed in the top of the bed 11 to hold the plunger 20 and with it the die 12 in accurate position on the bed 11. It will also be noticed that by the arrangement dcscribed the die 12 with the plunger 20 contained therein can be readily removed from the bed 11 to allow of moving the plunger 20 upward in the die to eject the finished powder puff from the die.

In the upper die 15 is mounted to slide a plunger 30 adapted to engage the top of the powder pufi' section 14 to push the same downward in the die 15 and into the upper end of the die 12 to unite the powder puff section 14 with the powder puff section 13 (see Figure 4). The sliding movement of the plunger 30 in the die 15 is limited by a set screw 31 screwing in the die and projecting into a vertical groove 32 formed in the peripheral face of the plunger 30. The upper portion of the plunger 30 is preferably made hollow and into this hollow portion projects a handle 33 attached to the bottom of the plunger and projecting upwardly to permit of conveniently sliding the plunger 30 from lowermost position, shown in Figure 4, to uppermost position, shown in Figure 3, at the time the die 15 is removed from the die 12. When the plunger 30 is in its uppermost position, as shown in Figure 3, then its top is preferably flush with the top of the die 15 while the under side of the plunger 30 is spaced from the bottom of the die 15 to provide suiiicient space for the reception of the powder puff section 14. It is understood that the powder puff sections 13 and 14 fit snugly into the dies 12 and 15, as indicated in Figure 3.

In using the press, the die 15 with its plunger 30 therein is removed from the die 12 to permit of placing a powder puff section 13 into the upper end of the die 1.2 and the powder puff section 14 into the lower end of the die 15, after which the die 15 is replaced on the die 12, as shown in Figure 3. When the dies are in this position the plunger 30 is moved downward for uniting the powder puff section 14 with the powder puff section 13. For this purpose the fol- .lowing arrangement is made: The upper end of the plunger 30 is adapted to be engaged by a plunger 40 having a stem 41 mounted to slide up and down in bearings 42' and 43' attached to or forming part of a standard 44 rising from the bed 11. A spring 45 is coiled on the stem 41 and rests with its lower end on the bearing 42 while the upper end of the spring engages a pin 46 attached to the stem 41 to normally hold the plunger 40 a short distance above the top of the upper die 15, as plainly shown in Figures 1 and 2. The upper end of the stem 41 of the plunger 40 is engaged by the free end of a lever 50 fulcrumed at 51011 the top of the standard and connected by a link 52 with a treadle 53 fulcrumed at 54 onthe lower portion of the stand 10. The treadle'53 is under the control of the operator standing in front of the machine. When the operator pushes the treadle 53 downward then a swinging motion is given to the lever 50 to cause the latter to move the plunger 40 downward against the tension of its spring 45 and when the operator releases the treadle 53 the plunger 40 returns to uppermost position by the action of the spring 45. It is understood that this return movement of the plunger 40 produces a return swinging movement of the lever 50 and treadl'e 53'.

The downward sliding movement of the plunger 40 is limited to limit the downward movement of the plunger 30 in the die 15 to prevent crushing of the powder puff sections 13 and 14. In order to limit the downward movement of the plunger 4-0 use is made of a stop collar 55 screwing on the upper threaded end of the plunger stem 41*,and this collar 55 is adapted to engage the top of the bearing 43 to limit the downward movement of the plunger 40. It is understood that by adjusting the collar 55 up or down on the stem 41 a longer or shorter sliding movement can be given to the plunger 40. After the collar 55 is adjusted to the desired position it is fastened in place by a set screw 56 and by a jam nut 57 screwing on the stem 41 and fastened in place by a set screw 58. It will he noticed that by the arrangement described a very minute adjustment of. the downward movement of the plunger 40 can be had to compensate for different thicknesses in the powder puff materials used in the powder puff sections 13 and 14 at the same time preventing crushing of the said sections when uniting the same. The stem 41 of the plunger 40 is prevented from turning in its bear ings 42 and '43 by a set screw 60 held on the bearing 42 and projecting into a groove 61 formed in the stem 41.

The particular powder puff sections 13 and 14 to be united are arranged as follows: The powder puff section 13 is provided with a ring of sheet metal, over which is stretched a body part- 71 of powder puif 1naterial. The ring 70 is provided at its inner edge with struck-up locking arms 7 2 spaced apart and with points 7 3 disposed diametrically opposite each other for receiving the ends of a handle 74 of ribbon or band ma terial. This handle extends across the outer face of the body part 71 and rests with the latter on the top of the plunger 20, as shown in Figure 3. The other powder puff section 14 comprises a metal ring provided with a return bent rim 81 and over this ring 80 and its rim 81 is stretched the other body part 82 of powder puff material. The ring 80 is preferably arched and when the section 14 is forced downward by the plunger 30' then the arms 72 engage the under side of the ring 80 adjacent the inner edge thereof whereby the arms '52 are bent outward into engagement with the rim 8] and the latter is pressed into contact with the inturned flange of the body part 71 to clamp the latter in place on the ring 70. Thus the two rings 70 and 80 are interlocked and the body parts 71 and 82 carried by the said rings are securely clamped in position, as will be readily understood by reference to Figure 4. If desired, suitable paddings of cotton batting or the like may be interposed hetween' the body parts 71, 82 and their rings 70 and 80 to give the desired fullness to the powder puff.

In using the press the die 15 is removed from the die 12 to permit of placing the powder putt sections 13 and 14 inposition in the dies 12 and 15, as previously men-- tioned, after which the die 15 is replaced on the die 12 and then the operator presses the treadle downward to cause the plunger 40 to engage the plunger 30 and move the latter downward to unite the powder pull sections 13 and 14 with each other, as above explained. When this has been done, the

operator releases the treadle 53 to allow the plunger 40 to return to uppermost position and then the operator removes the die 15 from the die 12 and lifts the latter off the.

bed 11 to permit the operator to push the plunger 20 upward into the die 12 to eject the finished powder puff from the die 12. The latter is then replaced on the bed 11 and another powder pufi section 13 is placed in the die, after which the other die 15 with a new section 14 therein is replaced on the die 12 and the above described operation is repeated.

From the foregoing it will be seen that by the arrangement described a large number of powder pufis or similar articles can be manufactured in a comparatively short time without requiring the use of highly skilled labor. It will also be noticed that the powder puff sections 13 and 14; are accurately united with each other and without danger of crushing or otherwise injuring the sections.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1.
